No worries, brake fluid is glycol based, steering fluid is petroleum based. Had you put PS fluid in the brake master ...that would've been a bigger seal issue.
I'd consider a follow up flush as a precaution, making sure to drain pump and rack by moving the steering wheel full rotations. Disconnect lines as necessary to facilitate this, engine off.
